There is always the common question on these message boards about how fast a typical person could run the 100m. To test our timing system out, the head track coach at my school had every student in a PE class warm up 2 laps and run the 100m. Only people who wore athletic clothes and shoes could participate, and it seemed like he ran male and female heats to make the data easier to read. I asked to see the results afterward at practice, and was surprised to find out that the average male time was 14.8 and female time was 18.5. This was from about 7 periods of class and around ~80 participants each period.
